If a user that uses systemd and dracut wants to overide certain settings, they typically use `systemctl edit [unit]` or place a file in `/etc/systemd/system/[unit].d/override.conf` directly. The zfs-dracut module did not include those overrides however, so this did not have any effect at boot time. For zfs-import-scan.service and zfs-import-cache.service, overrides are now included in the dracut initramfs image.
